Hi, was setting up this plugin to work with Nuvotifier but seem to be having issues. I kept getting "did you break the config? :(" messages but when I thought I finally fixed it I now get "Error occurred while executing command:2"

Any help would be great, still getting use to editing configs again (Been years) So if I made any dumb mistakes sorry xD

Server details: Pixelmon server, running latest sponge, 1.10.2 version, latest forge, latest sponge API, most/all plugins are up to date. Though I did notice that you just released 3.2 for seriousvote so will update that while I send this message.

config:
{
config-version: "3.0"
#//Variables - {player} : the person who voted
#// {rewards} : The list of random rewards the player received
#//Leaving this empty will disable messages from being shown publicly: Supports color and formatting codes
broadcast-message: ""
#//-1 will have the system select a number of rewards between rewards-min and rewards-max;

under random rewards if you don't want any than set the number to 0, it's missing the third "" so it's gonna throw an error if you're trying to use it.In the upcoming official build I'll be adding a check for that, so it will tell you it is messed up before trying to execute them.random-rewards-number: 0

# The IP to listen to. Use 0.0.0.0 if you wish to listen to all interfaces on your server. (All IP addresses)
# This defaults to the IP you have configured your server to listen on, or 0.0.0.0 if you have not configured this.
host: 0.0.0.0
# Port to listen for new votes on
port: 8192
# Whether or not to print debug messages. In a production system, this should be set to false.
# This is useful when initially setting up NuVotifier to ensure votes are being delivered.
debug: true

config:
{

To my knowledge all needed ports are open, the voting websites themselves detect and say the server are online and that voting is enabled/working, I mentioned earlier the server is a bungeecord server. All servers + the bungee have Nuvotifier and are all running the same config and the listening key being used is the Hub worlds, Hoping that its just a dumb mistake on my side that can easily be fixed, but willing to try any troubleshooting tips thrown my way, thanks!
